Approximating Attack Surfaces with Stack Traces [ICSE 15]Chris Theisen
Security testing and reviewing efforts are a necessity for software projects, but are time-consuming and expensive to apply. Identifying vulnerable code supports decision-making during all phases of software development. An approach for identifying vulnerable code is to identify its attack surface, the sum of all paths for untrusted data into and out of a system. Identifying the code that lies on the attack surface requires expertise and significant manual effort. This paper proposes an automated technique to empirically approximate attack surfaces through the analysis of stack traces. We hypothesize that stack traces from user-initiated crashes have several desirable attributes for measuring attack surfaces. The goal of this research is to aid software engineers in prioritizing security efforts by approximating the attack surface of a system via stack trace analysis. In a trial on Windows 8, the attack surface approximation selected 48.4% of the binaries and contained 94.6% of known vulnerabilities. Compared with vulnerability prediction models (VPMs) run on the entire codebase, VPMs run on the attack surface approximation improved recall from .07 to .1 for binaries and from .02 to .05 for source files. Precision remained at .5 for binaries, while improving from .5 to .69 for source files.

CE.RE.S: An Eclipse plug-in to evaluate source code readabilityGemma Catolino
During software evolution, change is the rule rather than the exception. It has been demonstrated as the maintenance phase costs 75% more than development costs. One of the reason of such a cost is about the effort of developers in understanding the source code produced in the development lifecycle. In this work, we designed a novel comprehensive model, namely CodE REadability in eclipSe (CE.RE.S), for measuring code readability. CE.RE.S enriches previous code readability metrics by considering textual (or lexical) aspects of source code, that are crucial for effectively capturing code readability. The proposed approach has been empirically evaluated through a controlled experiment involving ten university students and two industrial developers, and it was aimed at analyzing the benefits provided by CE.RE.S during software development and maintenance. The results achieved indicate that CE.RE.S helps developers improving overall readability of the produced source code, especially in terms of meaningfulness of the resulting identifier names.
With the development and rapid growth in IT infrastructure, malicious code attacks are considered as the
main threat to cybersecurity. Malicious JavaScript’s which are intentionally crafted by the attackers inside the web page
over the web as an emerging security issue affecting millions of users. In past few years, a number of studies have been
conducted based on machine learning for detection of malicious JavaScript code attacks has demonstrated a poor
detection accuracy and increased performance overheads. In this paper, an effective interceptor approach for detection of
multivariate and novel malicious JavaScript’s based on deep learning is proposed and evaluated. Hybrid feature set based
on static and dynamic analysis were used. The dataset which was used in this study consists of 32,000 benign webpages
and 12,900 malicious pages. The experimental results show that this approach was able to detect 99.01% of new malicious
code variants.

The article proposes two different designs for the new block cipher algorithm of 128-bit block size and key lengths of 128-bit or 192-bit or 256-bit. The basic cipher round is designed in a parallel model to help improve the encryption/decryption speed. The differences of this design compared to the previous one
developed on Switchable Data Dependent Operations (SDDOs) lies in the hybrid of the controlled elements (CEs) in the structure. Each design has a specific strength that makes the selection more compatible with the objectives of each particular application. The designs all meet the high security standards and possess the ability to fight off the attacks currently known. The designs match the limited environment of the wireless network by integrating effectively when implemented on Field-programmable gate array (FPGA) with both iterative and pipeline architectures for high effective integration.

Newly, the cyber security of vehicle ad hoc network (VANET) includes two practicable: vehicle to vehicle (V2V) and Vehicle to Infrastructure (V2I) that have been considered due to importance. It has become possible to keep pace with the development in the world. The people safety is a priority in the development of technology in general and particular in of VANET for police vehicles. In this paper, we propose a software engineering based self-checking process to ensure the high redundancy of the generated keys. These keys are used in underlying cyber security system for VANET. The proposed self-checking process emploies a set of NIST tests including frequency, block and runs as a threshold for accepting the generated keys. The introduced cyber security system includes three levels: Firstly, the registration phase that asks vehicles to register in the system, in which the network excludes the unregistered ones. In this phase, the proposed software engineeringbased self-checking process is adopted. Secondly, the authentication phase that checks of the vehicles after the registration phase. Thirdly, the proposed system that is able to detect the DOS attack. The obtained results show the efficient performance of the proposed system in managing the security of the VANET network. The self-checking process increased the randomness of the generated keys, in which the security factor is increased.

A source code security audit is a powerful methodology for locating and removing security vulnerabilities.
An audit can be used to (1) pass potentially prioritized list of vulnerabilities to developers (2) exploit
vulnerabilities or (3) provide proof-of-concepts for potential vulnerabilities. The security audit research
currently remains disjoint with minor discussion of methodologies utilized in the field. This paper
assembles a broad array of literature to promote standardizing source code security audits techniques. It,
then, explores a case study using the aforementioned techniques.
The case study analyzes the security for a stable version of the Apache Traffic Server (ATS). The study
takes a white to gray hat point of view as it reports vulnerabilities located by two popular proprietary tools,
examines and connects potential vulnerabilities with a standard community-driven taxonomy, and
describes consequences for exploiting the vulnerabilities. A review of other security-driven case studies
concludes this research.
Building a Distributed Secure System on Multi-Agent Platform Depending on the...CSCJournals
Today, applications in mobile multi-agent systems require a high degree of confidence that running code inside the system will not be malicious. Also any malicious agents must be identified and contained. Since the inception of mobile agents, the intruder has been addressed using a multitude of techniques, but many of these implementations have only addressed concerns from the position of either the platform or the agents. Very few approaches have undertaken the problem of mobile agent security from both perspectives simultaneously. Furthermore, no middleware exists to facilitate provisioning of the required security qualities of mobile agent software while extensively focusing on easing the software development burden. The aim is to build a distributed secure system using multi-agents by applying the principles of software engineering. The objectives of this paper is to introduce multi agent systems that enhance security rules through the access right to building a distributed secure system integrating with principles of software engineering system life cycle, as well as satisfy the security access right for both platform and agents to improve the three characteristics of agents adaptively, mobility and flexibility. This project based on the platform of PHP and MYSQL (Database) which can be presented in a website. The implementation and test are applied in both Linux and Windows platforms, including Linux Red Hat 8, Linux Ubuntu 6.06 LTS and Microsoft Windows XP Professional. Since PHP and MySQL are available in almost all operating systems, the result could be tested the platform as long as PHP and MySQL configuration is available. PHP5 and the MySQL (database) software are used to build a secure website. Multiple techniques of security and authentications have been used by multi-agents system. Secure database is encrypted by using md5. Also satisfy the characteristics for security requirements: confidentiality (protection from disclosure to unauthorized persons), integrity (maintaining data consistency) and authentication (assurance of identity of person or originator of data).
Software Reliability and Quality Assurance Challenges in Cyber Physical Syste...CSCJournals
Software Reliability is the probability of failure-free software operation for a specified period of time in a specified environment. Cyber threats on software security have been prevailing and have increased exponentially, posing a major challenge on software reliability in the cyber physical systems (CPS) environment. Applying patches after the software has been developed is outdated and a major security flaw. However, this has posed a major software reliability challenge as threat actors are exploiting unpatched and insecure software configuration vulnerabilities that are not identified at the design phase. This paper aims to investigate the SDLC approach to software reliability and quality assurance challenges in CPS security. To demonstrate the applicability of our work, we review existing security requirements engineering concepts and methodologies such as TROPOS, I*, KAOS, Tropos and Secure Tropos to determine their relevance in software security. We consider how the methodologies and function points are used to implement constraints to improve software reliability. Finally, the function points concepts are implemented into the CPS security components. The results show that software security threats in CPS can be addressed by integrating the SRE approach and function point analysis in the development to improve software reliability.

Internal security on an ids based on agentscsandit
An Intrusion Detection System (IDS) can monitor different events that may occur in a
determined network or host, and which affect any network security service (confidentiality,
integrity, availability). Because of this, an IDS must be flexible and it must detect and trace
each alert without affecting the system´s performance. On the other hand, agents ina Multi-
Agent system have inherent security problems due to their mobility; that’s why we propose some
techniques in order to provide internal security for the agents belonging to the system. The
deployed IDS works with a multiagent platform and each component inside the infrastructure is
verified using security techniques in order to provide integrity. Likewise, the agents can
specialize in order to carry out specific jobs, for example monitoring TCP, UDP traffic, etc. The
IDS can work without interfering in the system's performance. In this article we present a
hierarchical IDS deployment with internal security on a multiagent system, using a platform
named BESA with its processes, functions and results.

An explicit trust model towards better system securitycsandit
Trust is an absolute necessity for digital communications; but is often viewed as an implicit
singular entity. The use of the internet as the primary vehicle for information exchange has
made accountability and verifiability of system code almost obsolete. This paper proposes a
novel approach towards enforcing system security by requiring the explicit definition of trust for
all operating code. By identifying the various classes and levels of trust required within a
computing system; trust is defined as a combination of individual characteristics. Trust is then
represented as a calculable metric obtained through the collective enforcement of each of these
characteristics to varying degrees. System Security is achieved by facilitating trust to be a
constantly evolving aspect for each operating code segment capable of getting stronger or
weaker over time.
DEVELOPMENT OF SECURE CLOUD TRANSMISSION PROTOCOL (SCTP) ENGINEERING PHASES :...ijcisjournal
Cloud computing technology provides various internet-based services. Many cloud computing vendors are offering cloud services through their own service mechanism. These mechanisms consist of various service parameters such as authentication, security, performance, availability, etc. Customer can access these cloud services through web browsers using http protocols. Each protocol has its own way of achieving the request-response services, authentication, confidentiality and etc. Cloud computing is an internet-based technology, which provides Infrastructure, Storage, Platform services on demand through a browser using HTTP protocols. These protocol features can be enhanced using cloud specific protocol, which provides strong authentication, confidentiality, security, integrity, availability and accessibility. We are proposing and presenting the secure cloud transmission protocol (SCTP) engineering phases which sits on top of existing http protocols to provide strong authentication security and confidentiality using multi-models. SCTP has multi-level and multi-dimensional approach to achieve strong authentication and multi-level security technique to achieve secure channel. This protocol can add on to existing http protocols. It can be used in any cloud services. This paper presents proposed Protocol engineering phases such as Service Specification, Synthesis, Analysis, Modelling, and Implementation model with test suites. This paper is represents complete integration of our earlier proposed and published multilevel techniques

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

1 Introduction
Directly verifying security protocol code could help prevent major security flaws
in communication systems. C is usually used when implementing security soft-
ware (e.g. OpenSSL, cryptlib, PolarSSL...) because it provides control over
side-channels, performance, and portability all at once, along with being easy
to call from a variety of other languages. But those strengths also make it hard
to reason about, especially when dealing with high-level logical properties such
as authentication.
Verifying high-level code. The most advanced results on verifying imple-
mentations of security protocols tackle high-level languages such as F#. Two
main verification trends can be identified on high-level languages. The first
one aims at soundly extracting models from the program code, and using a
cryptography-specific tool such as ProVerif (e.g. fs2pv [BFGT06]) to verify that
the extracted protocol model is secure with respect to a given attacker model.
The second approach, on the other hand, aims at using general verification tools
such as type systems and static analysis to verify security properties directly
on the program code. Using general verification tools permits a user with less
expert knowledge to verify a program, and also allows a more modular approach
to verification, even in the context of security, as argued in [BFG10].
Verifying C code. But very few widely-used security-oriented programs are
written in such high-level languages, and lower-level languages such as C are
usually favoured. Several approaches have been proposed for analysing C secu-
rity protocol code [GP05, ULF06, CD08], but we believe them unsatisfactory
for several reasons:
• memory-safety assumptions: all three rely on assuming memory-safety

properties,1
• trusted manual annotations: all three rely on a large amount of trusted
manual work,
• unsoundness: both [CD08] and [ULF06] make unsound abstractions and
simplifications, which is often not acceptable in a security-criticial context,
• scalability issues: [CD08] is limited to bounded, small in practice, numbers
of parallel sessions, and we believe [GP05] is limited to small programs due
to its whole-program analysis approach.
1.1 Goals
Our goal is to provide a new approach to soundly verify Dolev-Yao security
properties of real C code, with a minimal amount of unverified annotations and
assumptions, so that it is accessible to non-experts. We do not aim at verifying
implementations of encryption algorithms and other cryptographic operations,
but their correct usage in secure communication protocols such as TLS.
2 Framework
Previous approaches to verifying security properties of C programs did not de-
fine attacker models at the level of the programming language, since they were
based on extracting a more abstract model from the analysed C code (CSur and
Aspier), or simply verified compliance of the program to a separate specification
(as in Pistachio). However, to achieve our scalability goals, we choose to define
an attacker model on C programs, that enables a modular verification of the
code.
To avoid issues related to the complex, and often very informal semantics of the
C language, we use the F7 notion of a refined module (see [BFG10]). In F7,
a refined module consists of an imported and an exported interface, contain-
ing function declarations and predicate definitions, along with a piece of type-
checked F# code. The main result states that a refined module with empty
imported interface cannot go wrong, and careful use of assertions allows one
to statically verify correspondence properties of the code. Composition results
can also be used to combine existing refined modules whilst ensuring that their
security properties are preserved.
We define our attacker model on C programs by translating F7 interfaces into
annotated C header files. The F7 notion of an opponent, and the corresponding
security results, can then be transferred to C programs that implement an F7-
translated header. The type-checking phase in F7 is, in the case of C programs,
replaced by a verification phase, in our case using VCC. We trust that VCC is
sound, and claim that verifying that a given C program correctly implements
a given annotated C header entails that there exists an equivalent (in terms of
attacks within our attacker model) F7 implementation of that same interface.

3 Case Study
We show how our approach can be used in practice to verify a simple implemen-
tation of an authenticated Remote Procedure Call protocol, that authenticates
the pair of communicating parties using a pre-shared key, and links requests
and responses together. We show that different styles of C code can be verified
using this approach, with varying levels of required annotations, very few of
which are trusted by the verifier. We argue that a large part of the required
annotations are memory-safety related and would be necessary to verify other
properties of the C code, including to verify the memory-safety assumptions
made by previous approaches.
4 Conclusion
We define an attacker model for C code by interpreting verified C programs as
F7 refined modules. We then describe a method to statically prove the impos-
sibility of attacks against C code in this attacker model using VCC [CDH+ 09],
a general C verifier. This approach does not rely on unverified memory-safety
assumptions, and the amount of trusted annotations is minimal. We also believe
it is as sound and scalable as the verifier that is used. Moreover, we believe our
approach can be adapted for use with any contract-based C verifier, and could
greatly benefit from the important recent developments in that area.
